IMPROVEMENT IN CARPET-FASTENERS.

Specification forming part of Letters Patent N 0. 188,818, dated March 27, 1877 application filed March 6, 1877.

To all whom it may concern Be it known that I, AN'roNIo ROSELLO, of

Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Carpet-Fastener; and

I dohereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw- I and hold a plate to be fastened to the carpet,

substantially in the manner hereinafter set forth.

In the annexed drawing, Figure 1 is a perspective view of the screw. Figs. 2, 3, 4, and 5 show various forms of plates to be held in the screw. Fig. 6 shows a tang that may be used to fasten the plate to the carpet. Fig. 7 shows a plate fastened in the screw.

A represents a screw of ordinary form, the head Bof which is provided on top with a dovetailed tapering groove, b, extending entirely across the same. In the bottom of this groove is a straight groove, a, adapted to receive the end of a screw-driver, so as to remove the screw, even if the head should be broken-that is, if either of the lips formed by the grooveb should be broken off. The screw A is to be screwed down vertically into the floor, or horizontally into the wash-board, as desired. D represents the plate that is to be fastened to the carpet,

' and is provided with a dovetailed tapering lug, d, to be drawn into the slot b in the screwhead B. This lug d may be formed on the un' der side of the plate D, to be used when the screw is inserted in the floor; or the lug may project from the edge of the plate, to be used y when the screw is inserted in the wash-board.

The plate D may be fastened to the carpet in various ways. One or more tangs, 0, may be formed in one piece with the plate, as shown in Figs. 2, 3, and 7, said tang or tangs being passed upward through the carpet, and then bentdownward through the carpet and through a slot, at, in the plate. Or, the plate may be formed with two slots, av 00, as shown in Fig. 4, without a tang, and a separate tang, Gr, used, one end of this tang being pointed, and the other end bent to form the head G. This tang is then passed up through one of the slots :20, and then fastened in the same manner as described above. Or, if desired, the plate D may have a series of holes, y, so that the plate can be sewed to the carpet, instead of fastened with tangs. These plates D are -fastened at any suitable intervals to the edges of the carpet, and the screws A being fastened at corresponding intervals to the floor or washboard, the carpet can be easily put down and taken up when desired.

The plates can be struck up by dies, or formed by any other suitable means, and when the carpet is worn out, or has to be changed from one room to another, the plates can easily be taken off the carpet and put on again.

I prefer to' make the holder a screw, as shown; but it may be made in form of a tack or nail, instead of a screw, and not depart from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a carpet-fastening, a screw, A, having a head, B, provided with a dovetailed tapering groove, b, adapted to receive and hold a plate, D, fastened to the carpet, substantially as and for the purposes herein set forth.

2. In a carpet fastening, the plate D, provided with a dovetailed tapering lug, d, and fastened to the carpet by one or more tangs, or otherwise, in combination with a screw having a grooved head adapted to receive said lug, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

ANTONIO ROSELLO.
